To 15 whom it may concern.-

Be 1t known that 1, WILLIAM R. llmcrrr a subject of the King of GreatBritain, and

a resident of. Belleville, county of Essex and State of New Jersey, haveinvented new and useful Improvements in Playing-Balls of which thefollowing is a specification.

The object of the invention is to construct a playing ball with meanswhich will place the hall under control in all departments of the gan'iein which. it is employed.

According to my invention the ball may be provided: with a: centerhaving a heavy liquid that will aid its flight.

' The invention preferably relates to that class of playing-balls thatare (specially adapted for the purpose of golfing and which have aliquid center. In performing my invention a playing-ball is constructedwith a bag or container within which there are liquids of differentspecific gravities. The weight of the ball is dependent to a certainextent upon the particular combination of: liquids chosen and the amountof each liquid employed. With the proper selection of liquids a ball maybe made comparatively heavy; that is the ball may be what is known as anon-floating ball or the ball may be made comparatively light, that isthe ball.

may be what is known as the floating type of ball.

As illustrating the manner in which the invention may be realizedreference is made to the accompanying drawing which forms a part of thisspecification and in which drawing- Figure 1 illustrates a playing-ballpartially broken away so asto show its interior construction. Fig. 2shows a core partially broken away which is utilized in the ball shownin Fig. 1.

The playing-ball comprises a bag or container A that is filled withincompressible liquids of diilerent specific gravities as B and F, Bbeing the lighter liquid and F the heavier liquid. The bag or containerA and the liquid thus constitute the nucleus'or core of the ball. Aroundthis core there is preferably wound under a high degree of tension arubber tape that may be for example approximately one inch in width.This rubber tape is comparatively thin. and when wound under a highdegree of tension imparts great pressure upon the liquid in the bag orcontainer A. The windings of tape are indicated by the referencecharacter Q and around these windings of tape there is wound under ahigh degree of tension what may -be considered a thread of rubber whichthread before winding may be approximately three thirty-seconds of aninch in width. These windings of rubber thread are indicated by thereference character l3. Finally there is placed upon and around thesewindings any suitable wear-resisting casing E, for example of guttapercha, which constitutes the exterior portion of theball. The bag orcontainer' A is made so as to comprise the rubber portion a and fabricportion a) that con stitutes arcinforcing member or protecting memberfor the rubber in the casing.

It has been. previously indicated that any one of several combinationsof liquids may be employed within the bag or container A, dependent uponthe kind of ball ultimately desired. For example, it a heavy ball isdesired the liquid within the bag or container A may comprise atcr forthe lighter liquid 13 and mercury for the heavier liquid F. It a ball ofa difi erent weight is'desircd acetylene tctrabromid may be employed forthe heavier liquid, and amyl formate tor the ligl'itcr liquid. Theformer of these has a specific gravity of approximately and the latter aspecific gravity ot approximately .868. If a floating ball is desiredheptanc may be employed for the lighter liquid and amyl formats for theheavier liquid. The specific gravity of hcptanc is approximately .689While that of amyl for-mate as above indicated is approximately .868.Other coinbinations which might be used are as follows but it will beunderstood that a large number of combinations could be employed. otherthan those indicated in this specification. Methyl salicylate and ainylformats the relative specific gravities of which are respectively 1.185and .868. Heptane and water the relative specific gravities of which areapproximately .689 and 1.00.

The liquids in the different sets of combinations above referred to arenot soluble in each other; in other words they are of such a characterthat they do not tend to mix but on the other'hand tend to separate andremain separated with the lighter liquid lloating' on the heavierliquid, and the expression do not mix with each other is intended toconvey the meaning that these liquids will tend to separateand tend toremain sepa rated if allowed to do so.

it will be manifest that the invention may be embodied 'in'various formsand modifications Without departing from the spirit and scope thereof. b

What I claim is:

1. A playing-ball comprising in combination a bag or container filledwith a plurality of liquids of: different specific gravities, windingsof rubber surrounding said bag, and a Wear-resisting casing on theexterior of said windings.

2. A playing-ball comprising in combination a bag or container filledwith liquids of different specificigraviti'es which liquids are of sucha character that they tend to separate from eachother, rubber windingssurrounding said bag or container, and Wearresisting casing on theexterior of said Windings. p

A playing-ball comprising inbombination a' bagorcontainer having thereina plurality of liquids of difierent specific Vgravities and whichliquids are of such character that they do not mix With each other,windings surrounding said container, and a Wear-res1st1ng casingsurrounding said windings. A

i. A playingball comprising in combination a bag or container havingtherein 1ncompressible llqulds of different specific ,gravities,windingssurrounding said container, and ,a Wear-resisting casing.surrounding said-windings.

5. A playing-ball having in combination a bag or container comprising-alayeroi' rubber and a layer oi material to protect said rubber, aplurality ofhquids one of which is mercury contained in said bag, Windins of rubber about said bag, and a Wear-res1stwearer.

6. A play1ng-ball having a core which comprises a bag having a layer offabric or other reinforcing material and a layer of rubber, a pluralityof incompressible liquids in. said bag of difierent specific gravities,windings about said bag, and a Wear-resist ing casing constituting theouter portion of the ball.-
